Now to the story we can't get enough of this morning. Imagine waking up from your plane ride, and everyone is gone. To passengers, no crew. And the doors are locked. For one man, it was reality. Rob nelson has been following this story and joins us this morning. So many people wondering how this could happen, rob? Reporter: That's great question. Good morning, bianna. The film a few years ago, tom hanks, the terminal. Tom got lost in the airport. For one louisiana guy, that hits home. In the real-life version, that guy never made it off the plane. Overnight, winter weather pounded the nation, leaving thousands stranded at the airport. So we're canceling flight 909 due to severe weather in chicago. Reporter: But weather didn't stop tom wagner from catching his flight. It was because he was catching Zs. I woke up. The lights were out. I was like, what's going on? Reporter: He was headed from louisiana to california with a layover in houston. Prepared to meet his sister in orange county, he woke up in his seat near the back of the plane, freezing, all alone, in a dark, empty cabin. I called my girlfriend. She shaugt I was crazy. I said debbie, I'm locked on a plane. Reporter: Express jet is investigating to determine how this occurred. We sincerely apologize for the inkconvenience this passenger. What if the I had a heart attack and was dead? Reporter: He's flying the SAME AIRLINES ON DECEMBER 15th. He's learned if you snooze, you lose. Now, wagner did eventually get a voucher for a hotel room and another flight. Just to be safe, when that plane finally got to california, they announced his name over the intercom to make sure that time he did get off the plane. Dan and bianna? The stewardesses were bringing him coffee throughout the flight. Rob, crazy story. Thanks. Well time now for the weather.
